enter your answer in the box.
ages of volunteers
histogram with age on x - axis (10 - 14, 15 - 19, 20 - 24, 25 - 29, 30 - 34, 35 - 39) and number of volunteers on y - axis (0 - 10). bars: 10 - 14: 3, 15 - 19: 2, 20 - 24: 7, 25 - 29: 8, 30 - 34: 5, 35 - 39: 5

Explanation:

Step1: Find total volunteers

Sum the number of volunteers in each age group:
10–14: 3, 15–19: 2, 20–24: 7, 25–29: 8, 30–34: 5, 35–39: 5.
Total = \( 3 + 2 + 7 + 8 + 5 + 5 = 30 \).

Step2: Find volunteers 15–24

Sum 15–19 (2) and 20–24 (7): \( 2 + 7 = 9 \).

Step3: Calculate percentage

Percentage = \( \frac{\text{15–24 volunteers}}{\text{Total volunteers}} \times 100 = \frac{9}{30} \times 100 = 30\% \).

Answer:

30%
